METHOD OF AND MACHINE FOR RANDING HEEL BLANKS.

Application filed August 23, 1923. Serial No. 658,853.

To (ZZZ whom it may concern:

Be it known that I, DnNNis PARKS, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented new and useful Improvements in Methods of and Machines for Handing Heel Blanks, of which the following is a specification.

This invention relates to the art of heel building, and has for its object the provision of a novel machine and co-operating mechanism for use in holding a rand strip on a heel blank, shaping the rand strip to the configuration of the heel and simultaneously pressing it upon the heel blank and, finally, cutting off the ends of the rand flush with the breast of the heel; the rand, be fore its application to the heel blank, being pasted on one side, or paste being applied to the heel blank in the space to be occupied by the rand, whereby, after the application of pressure to the rand, the same will be firmly secured upon the heel blank.

The invention also relates to a novel method of procedure, involved in applying and securing rands to heel blanks.

In order that the present invention may be better understood, I will first refer briefly to certain existing conditions in this art.

All, bent rands now employed have at least one common characteristic, and that is, the inside or thin portion of the rand is provided with folds or tucks so as to enable the rand better to assume a heel shape.

A certain percentage of the rands are put on the heels without any preparation other than this crimping or tucking, and the almost universal method employed for applying the crimped rand to the heel is by tacking. After the rand has been tacked onto the heel, the ends of the rand are cut off flush with the breast of the heel.

In all methods employed at present, therefore, there are at least three steps, namely, crimping, tacking, and butting, or cutting off the ends of the rand.

A fourth step is sometimes employed, which consists in molding the rand. This is effected by bending the rand into hee shape, and then applying pressure thereto to make it retain that shape as much as possible. lhe result of molding is that the rand acquires slightly more of a heel shape than the crimped rand, and is, therefore, easier to handle at thetacking machine, and

probably results in an improved quality of work. The disadvantage is, of course, that it adds an extra operation.

lVith the present invention, the necessity for molding the rand is eliminated, and the other steps, with the exception of crimping, are. performed on a single machine, and as parts of a continuous operation. In other words, I shape the rand to the heel, and while in that shape press it on and secure it to the heel, thereby etli'ccting, in a single operation, more even and uniform results than could previously be obtained in three or four separate operations.

In a prior application filed by me on the etth of June, 1923, Serial No. 643,204, I have described and claimed a machine and method of applying, molding and securing rands on heel blanks, and for cutting off the ends of the rands flush with the breast of the heel, in the use of which machine and the practice of which method, the rand is first moistened, paste applied to one side thereof, the rand then bent into heel shape in a mold by the lingers of the operator, and the moist and pasted rand then subjected to pressure, automatically applied, to mold it and secure it in position on the heel blank. Although the invention is being used successfully, too much time is consumed by the operator in the lingering or manual shaping of the rand, to causeit to conform to the mold.

According to my present invention, this fingering or manual shaping of the rand is entirely eliminated. The rand is inserted in the machine on the heel blank. and while held at the back, is pressed in all around, by suitable mechanism, until it conforms exactly to the shape of the heel. Then, the machine automatically presses and secures the rand onto the heel.

A further disadvantage of my prior invention resides in the fact that the rand has to be dampened in order to enable it to be manipulated to conform totlie shape of the contour of the heel blank, and, as is well known in the art, heels cannot be compressed when damp, and, therefore, the heels coming from this prior machine have to be dried out before the compressingoperation. This requires a considerable amount of floor spa e for drying purposes, and, of course, more time for the randing operation.

One of the characteristic features of the present invention, therefore, is a machine and mechanism for, and method of, automatically shaping the rand to the contour of the heel blank, while dry, and simultaneously applying or securing the rand to the heel blank While in this shape.

Another leading feature of the iliVBlltiOll is a presser foot, operating in two stages; first, to hold the rand in position on the heel blank, and, after it has been shaped, to press said rand firmly upon the heel blank.

Another characteristic feature of the inventionis the provision of a presser foot constructed in two parts, an outer and an inner, theinner part being normally positioned above theouter part, whereby to provide space for the crimped portion of the rand, which tends to buckle or turn up as the and is bent to the curvature of the heel blank, and which inner part, in the operation of the machine, is forced downward to the plane of the outer part, so as to press the crimped portion and all of the inner edge portion of the rand firmly upon the heel blank. 1

By reason of the pressure of the inside portion of the presser foot, the rand is given a permanent set and is pressed down firmly upon the heel blank, so as to make the adhesive eifective and to prevent the rand from springing up out of the container when the presser foot returns to its original position out of contact with the rand. \Vithout this final pressure, it has been found that some rands have a tendency to spring out of the holder when the presser foot is allowed to go back to its original position.

Another leadingv feature of the invention is the provision of tripping mechanism that co-ordinates the forward motion of the formers or wipers, which bend the rand into heel shape, with the interlocking mechanism of the machine, causing the mechanism to trip and force the presser foot into engagementwith the rand on the'heel blank only when the wipers or shapers have come to the end of their, forward movement.

Finally, a feature of the present invention is the provision of at least two holding pins for engaging the'central or rear portion of .the rand, so as to avoid the formation ofan angular bend when shaping the rand, which results when only a single contact or holding pin is employed.

The above enumeration of the objects or leading characteristics of the inventiomare not intended to be exclusive, and other-objects, characteristics and advantages of the invention will appear in the course of the full description of the invention toifollow.

My invention is illustrated in the accompanying drawings, in which V Figure 1 is a view in front elevation of a machine constructed according to Jay invention, and by the use of which my improved method of randing heels or heel blanks may be practiced;

Figure 7 is a similar view, but showing the-shaping device pulled forward to the shaping position.

As in the case of the machine illustrated in my prior application referred to above, the machine forming the subject matter of the present invention embodies the principle of operation of the lift-cutting machine described and claimed in my prior Patent No. 1,297,899, dated March 18, 1919, in that the plunger, or presser foot,is moved into the ieel blank holder by hand or foot power, after which it automatically interlocks with mechanism which causes the operation to be completed by the machine itself. The pur pose of this arrangement is to reduce, far as possible, the danger of accident, by preventing the hand of the operator from being caught between the presser foot and the top of the holder.

The machine comprises a frame consisting of side members 1, connected by frame bars 2, the lower portion of the side frame members being provided with legs, or standards, 3, on which the machine rests. Mounted centrally of the frame of the machine is a logholder 4 of the usual construction, the upper end of which is secured to the underside of a table or bed 5, 011 either side of which are mounted bins 6 for receiving the heel blanks to be randed. Secured on the table 5 in aliuement with the log-holder 4 is a heel blank holder 7, for receivingyin succession, the heel blanks to be randed. This holder is secured on the upper side of the table 5, and the latter rests upon the upper ends of adjusting screws 8, by turning which, in one direction or the other, the holder '4' may be adjusted to the proper height reiative to the movement of a presser foot 1).. This presser (toot, which will later he more 1d, a belt (not shown), driven from any suitable source of power, being movable through the medium of a belt shifter 15 to either of said pulleys, in the usual way. Mounted on the shaft 12 are two cams 16. Mounted above the cross-head 10 to slide on the ways 11 is a frame plate 17, which has mounted in its upper ends (Figure 2) a cross-shaft 18, which affords bearings for rollers 19, which are normally in engages ment with the cams 16. Such engagement is maintained through the medium of springs 20, secured at their upper ends to the frame plate 17. This plate, with the parts mounted thereon, as hereinafter described, is adapted to be continuously reiprocated by the co-action of cams 16 and springs 20 as the shaft 12 isrotated, the springs 20 maintaining the rollers 19 in contact with the cams 16 at all times, and yielding to allow the plate to be lowered under the action of said cams.

Pivotally mounted on the frame plate 17 is an actuating plate 21, (Figures 1, 2 and 3), this plate having lugs 22 projecting from its rear side at the top, which extend through apertures 23 of the frame plate 17. At either side, at its upper end, the plate 21. is'provided with ears 2d, over which engage coil springs 25, the lower ends of which are secured to the lower end of the frame plate 17.

Provided on the front of the cross-head 10 is a shouldered projection 26, and when the cross-head 10 is lowered, the actuating plate 21 is adapted to have its lower edge moved into and out of engagementwith the shoulder 26 to depress the presser foot by the action of the machine. For this purpose, there is pivotally mounted centrally of the plate 17 a dog 27 having an integral lever arm 28 extending through an opening 29 in the frame plate 17. The lower end of dog 27 is normally drawn inward or toward the plate 17 by means of coil springs 27, secured at their lower ends to the frame plate, and at their upper ends to projections 27 on opposite sides of said dog. Secured on the rear side of the cross-head 10 is an upright arm 30 which is guided in a bearing 31,'provided on the rear side of the frame plate 17. Loosely secured at its upper end on this hearing is a depending rod 32 (Figure 3), the lower end of which is adapted to be engaged by a moving part 'to cause the arm to come in contact with the lever arm 28 to release dog 27 from engagement with a lug 33 (Figures 2 and. 3)

on the front end of actuating plate 21.. The presser foot 9 and cross-head 10 are lowered through the medium of rods 34:, connected at their upper ends to brackets 35 (Figure 2) on the lower end of the crosshead 10 and connected by treadles 36, one or the other of which may be used according as it is more convenient for the operator.

Coil springs 87 are connected at their lower ends, respectively, to the rods 3%, and attheir upper ends to the frame of the machine, which tend norn'ially to raise the rods 3% and treadles 36 and thereby hold the cross-head 16 and plunger 9 in an elevated position. The presser foot 9 is of special construction, and the same will now be described, referring particularly to Figures 3, -l and 5.

The said presser foot comprises a casting 38 which is recessed on its upper side to rc ceive a foot-piece 39 on the lower end of the cross-head 16 to which it is secured by set screws 40. At its front end, the casting has a. downwardly depending portion 11, to which is secured a brass plate 42, which is bent at right angles to extend over the bottom edge of the depending portion 41, as indicated at 43, the latter serving as a cutting block to engage the cutting edge of a cutter 44: mounted in the front wall of the holder 7 Secured on the underside of the top of casting SS is a curved or U-shaped member 15, the opposite walls or legs of which are slotted, as indicated at 1-6. Loosely mounted on and sin-rounding the men'ibcr To is a heelshaped member 17, which operates, first, as a rand-holder, and then, with the member 46, as a plunger or presser foot to press the rand firmly against the heel blank and simultaneously force the randcd heel blank downward in the holder 7. The member 11-7 is supported by a pin 4.8, which passes through the slots 1-6 and is secured in the walls of the member -17.

As shown by Figures 3 and 5 the front or breast side +19 of the member -'l( of less height than the remainder of said member, and the walls of the U-shapcd member 4:") are cut away to form projections 50, which extend over the front wall 19 at adistance therefrom. The upper edge of the remain ing portion of the wall of member 47 is normally positioned at some distance below the underside of the top of casting 38, and the lower edge of member 17 extends below the lower edge of member 45. Thus, when the presser foot, as a whole, is moved downward, the lower edge of the member 17 will first engage the rand, and, afterward, the U-shaped member 15 will more downwardly into engagement with the rand. The member 47 falls to the lower position shown by gravity and is raised against the resistance of a coil spring 51 interposed between the casting 38 and the pivot pin. 18, The manncr of mounting the member 47 allows the same to rock slightly on the pivot pin 48, as will be understood.

In proceeding to rand a heelblank according to my invention and with the use of 'my improved machine, the rand strip is first placed on the heel blank and held at its center at the rear of the heel blank by the member 47, as hereinafter explained, and then the shaping device is n'ianipulated to force the side portions or legs of the rand into position on the heel blank between the latter and the presser foot. The mechanism for performing this operation will now be lescribed, referring more particularly to Figures Gand 7.

Projecting from the rear of the mold 7 is a flat support 52 which, likewise, projects laterally from the sides of said mold, as shown more particularly in Figure 6. The edges of this support are inclined or undercut, as indicated at 53 in Figure 4, and slidably mounted on this support is a slide plate 54 which is in the form of a plate provided in its forward edge portion with a heel shaped recess 55, and at its forward end, at opposite sides, with handles 56. On its underside, the plate 54 is provided with a groove 57 which embraces the inclined edges 53 of support 52. By grasping the handles 56, the plate 54 may he slid back and forth on the support 52, as will be understood. Mounted on the slide plate 54 is a contact member 58 which has a foot-piece provided with a slot 59 by which it is adjustably secured in position on the slide plate 54 by screw 60. The contact member 58 is designed in practice, to engage the arm 32 to trip dog 27 when the slide plate 54 is moved to the forward position, or that shown in Figure 7.

The numeral 61 indicates a stop, which is provided on the support 52 adjacent the edge of the holder 7. In practice, this stop serves to assist the ope ator in positioning the rand on the heel blank.

In operation, the rand, being placed in position on the'heel blank, as shown in Fig ure 6, the operator presses down on treadle 36 to bring the holding member 47 of the presser foot into engagement with the rand and hold it in that position while tire slide plate or shaper 54 is pulled forward to force the ends of the rands into heel shape, as shown by Figure 7.

It is one of the features of my invention that the rand. is curved or rounded at its rear side instead of being given an abrupt bend by the action of the shaper 54. This, I accomplish by providing a plurality of short pointed projections or spikes 62 (Figures 3 and 4), the drawing showing four of such spikes. Two or three spikes, however, might serve, the object being to grip the rand at at least two points beyond its center or point of bending so as to compelruptly. In other words, the rand is thus bent about two points instead of a single point.

T have referred to the U-shaped or inner member of the presser foot as having its lower edge located above the lower edge of the outer member or heel-shaped holder 47. This position of these parts is shown particularl in Figures 3 and 5, and it will be seen that when the member 47 is in position on the rand, as shown by Figure 5, a space 63 will be provided above the rand, and this space will. accommodate the crimped edge of the rand as the latter is turned inward by the shaper, this crimped or inner edge portion tending to buckle up, and, under any circumstances, requiring aspace to accommodate it in order to permit the rand to be easily curved into position on the heel blank.

In order to permit the shaper 54 to move to a position over the holder so that the in nor edge of the recess will correspond with the inner edge portion of said holder, 1 provide at the center of said recess 55 and on the underside of the slide plate 54 a recess 64 (Figures 4 and 5), which will receive the stop 61 and thus, as stated, will permit the plate 54 to be moved to the correct shaping position.

The holder 7, heretofore referred to, has, preferably, the size and shape of the heel blank to be randed, and comprises a U shaped wall 65 (Figure 6), corresponding to the rounded portion andsides of the heel blank, and a front "all, corresponding to the breast of the heel blank, the upper edge of which is sharpened to providea cuttter, this wall having previously been indicated as a cutter by the numeral 44 (Figures 4 and 5). The presser foot 9, as to the members 45 and 47, has its bottom surface shaped to conform to the configuration of the upper surface of the heel blank with the rand applied, that is to say, its side portions are upwardly inclined to correspond with the incline 0r taper of the upper surface of the rand, indicated in all the figures, where shown, by the numeral 66.

The depending portion, or cutting block, 41 of the presser foot, with its soft metal covering 43, is designed to co-operate with the cutter 44. By turning the adjusting screws 8, the height of the holder 7 may be so regulated that in the downward movement of the presser foot 9, the metal plate 43 will engage the cutter 44 with sutlicient firmness to completely sever any material placed between the said cutting block and cutter.

As shown by Figure 4, the knife edge of cutter 44 is located below the plane of the upper surface of holder 7. This permits a heel blank to be inserted from the front of the holder and the outer member 47 of the presser foot is of a size to be received snugly into the holder when the presser foot is lowered.

In operation, a heel blank, such as indicated at 67, (Figures 3 and 4), is placed in the holder 7, its breastedge engaging behind the cutter 44. A rand, having first had paste applied to its underside, is then placed on the heel blank, being moved by the open ator against the stop 61 (Figure The operator new places his foot upon treadle 3t; and lowers the cross-head 10 and presser foot 9. In this movement, the lower edge of the rear portion of the member 47 of the presser foot engages the rand 66, the spikes 62 piercing the rand and holding it in position on the heel blank. The operator now grasps the handles 56 of the shaper 54 and draws the latter forward. In this movement, the corners of the recess 55, which, as indicated by dotted lines in Figures 6 and 7 and in full lines in Figure 4 at 68, is undercut, engages the outer edge of the rand and gradually forces the same under the lower edge of the member 47 into position on top of the heel blank, forcing the and to assume a curved position, as indicated in Figure 7, with the ends 69 of the rand projecting over and beyond the cutter 44'. In this movement of the slide plate or shaper 54, the contact member 58 engages the lower end of arm and gradually moves it in ward. The position of the contact member is so adjusted on the said slide plate that as the latter reaches the position shown by Figure 7, in which the shaping and positioning of the rand is completed, the arm 32 will have been moved by said contact member into engagement with the lever arm 28 and press the same inward to throw dog 27 out of engagement with lug 33.

As the downward movement of cross-head 10 has operated to carry the projection 26 below the lower edge of the actuating plate 21, when the dog 27 releases lug 33, the springs 25 act to throw the lower end of plate 21. inward above projection 26, and as the frame plate 1'? moves downward under the action of'cams 16, the cross-head 10 and presser foot 9 will be forced downward to bring the bottom of the presser foot into engz ement with the rand and to force the randed heel blank downward in the logholder 4.

In this downward movement of the crosshead 10, the outer member 47 of the presser foot, being in engagement with the rand, will remain relatively stationary, while the inner member 45 of the presser foot will be forced downward against the resistance of spring 51 until the bottom of casting 38 and the bottom edge of the projection 50 engage the upper surface of member 47, whereupon the presser foot,asawhole, presses the rand into engagen'ient with the heel blank, and forces the randed heel blank into the holder. In this movement of the presser foot by the machine, as distinguished from the lowering of the presser foot by pressure on treadle 86, the inner member 45 of the presser foot engages the crimped inner edge portion of the rand and forces it into lirm engagement with the heel blank, so that all portions of the rand are pressed into firm engagement with the heel blank and the crimps in the rand are, to a large extent, pressed flat. As the presser foot reaches the lower limit of its movement, the plate 43 will engage the projecting ends 69 of the rand and force them over the cutter 44 to sever such ends flush with the breast of the heel blank.

As the lower edge of actuating plate 21 engages the shoulder 26, the plate will be forced upwardly a slight distance, due to the size of the openings 23, and when the operator releases the handles 56 of the slide plate or shaper, the springs 27 will turn the dog 27 into engagement with the lug b3 and simultaneously, through the lever arm 28, throw the arm 32 and slide plate 54 to the rear. This result may be facilitated by making the arm 32 a spring arm. As soon as the cams turn to release the pressure on rollers 19, the springs 20 raise frame plate 17, and, consequently, actuating plate 21, and the resulting pull of the dog 27 on the lug 33 turns the bottom of actuating plate 21 out of engagement with the projection 26, and when the treadle 36 is released, said projection 26 can move upward without engaging the bottom of plate 21.

In the downward movement of the presser foot, the rand is pressed firmly into engagement with the surface of the heel blank, and as the bottom of the presser foot, as a whole, conforms in shape to the upper surface of the randed heel blank, the presser footacts not only to press the rand uniformly into engagement with the surface of the heel blank, but to shape and smooth the upper surface of the rand, so that the finished heel blank, as to this feature, resembles very much such a heel blank after it has been subjected to the action of a compress. As the heel blanks are randed in the manner described, they are, in succession, forced downward in the log-holder 4, which may be of any desired length.

It will be observed that the operation of securing the rand upon the heel blank is performed in three stages; namely, first holding the rand; second, shaping the rand, and. third, pressing the rand; and that the machine, herein shown and described, lends itself admirably to these operations inasmuch as the holding and shaping of the rand is performed by the exercise of manual power, and the great power of the machine space to be occupied by the rand.

necessary to press or flatten the rand and force the randed blank downward. in the logholder, thereby moving a column of greater or less length through said log-holder, is automatically brought into play by the movement of the shaping device as soon as the rand has, by it, been shaped and positioned on the heel blank. 7

. At the same time, it should be understood that, so far as the method or the broad principle of my invention is concerned, I am not restricted in use to the machine herein shown and described, as any machine which w1ll enable the rand to be held, then automatically shaped, and, finally, pressed in position on the heel blank will come within the scope and answer the purposes of the invention.

In the application of paste, I have either applied paste to the underside of the rand itself or to the top of the heel blank in the For the sake of brevity, I have referred in the claims to the use of a pasted rand, and I intend, by such expression, to'cover either mode of pro- .cedureindicated, as, of course, so far as the present invention is concerned, it is a matter of indifference whether the paste be applied to the heel blank and the rand applied, or whether the rand be first pasted and then applied to the heel blank.
